Abstract: The optimal power flow problem is one of the most widely used problems in power system optimizations, which are multi-modal, non-linear, and constrained optimization problems. Effective constrained optimization methods can be considered in tackling the optimal power flow problems. In this paper, an ? -constrained method-based adaptive differential evolution is proposed to solve the optimal power flow problems. The ? -constrained method is improved to tackle the constraints, and a p -best selection method based on the constraint violation is implemented in the adaptive differential evolution. The single and multi-objective optimal power flow problems on the IEEE 30-bus test system are used to verify the effectiveness of the proposed and improved ? adaptive differential evolution algorithm. The comparison between state-of-the-art algorithms illustrate the effectiveness of the proposed and improved ? adaptive differential evolution algorithm. The proposed algorithm demonstrates improvements in nine out of ten cases.
